Abstract

A method of allocating resource elements in an orthogonal frequency division multiplexed (OFDM) system for transmission of a channel state information reference signal (CSI-RS) without overlapping with resource elements allocated to a port-5 user equipment-specific reference signal (URS) signal is disclosed. The method can include shifting in a frequency domain at least a portion of resource elements allocated to the CSI-RS in a normal-CP subframe. According to certain embodiments, the allocation of resource elements can be defined per an 8-port CSI-RS, or per a group of eight CSI-RS resource elements, within a single physical resource block (PRB) whose time-domain dimension is one subframe and whose frequency-domain dimension is 12 subcarriers.
